The list of inputs and outputs is as follows:

IP₀ Coin slot sensor        OP₀ Coin hold solenoid
IP₁ Cola drink button    OP₁ Coin accept solenoid
IP₂ Lemon drink button   OP₂ Dispense cola drink solenoid
IP₃ Cherry drink button   OP₃ Dispense lemon drink solenoid
IP₄ Lime drink button      OP₄ Dispense cherry drink solenoid
IP₅ Reject coin button     OP₅ Dispense Lime drink solenoid

The operation of the Soft Drinks Machine is as follows;

When a coin is clicked on with the mouse it is placed into the slot, it then operates the coin sensor IP₀. This should operate OP0 (coin hold solenoid), which will hold the coin in place. At this point either a drink is selected or the coin rejected.

The rejection of a coin is by operating IP₅, which should reset OP₀ allowing the coin to fall into the rejection box. If a coin is rejected, pointing the mouse at the coin and clicking resets the machine.

If a drink is selected by the operation of one of the drink select buttons, OP₁ (coin accept solenoid) should operate. This allows the coin to fall into the Kept box. Once the coin has dropped into the box, the solenoid corresponding to the selected drink should operate, allowing the drink to be dispensed.

Once the selected drink has been dispensed, clicking the coin will reset the machine.

Important Notes: When writing the program you must ensure that:

(a) The coin cannot be rejected once a drink has been selected.

(b) Selecting a drink disables all of the other drink buttons.

As usual, use the listed inputs and outputs and any flags, timers, and counters you require to complete the assignment. Use the documentation facilities to describe the program function.
